Men who lift weights may have more to gain than bigger biceps: A new study finds pumping iron may protect men against Type 2 diabetes.

The study, published online August 6 in the Archives of Internal Medicine, involved 32,000 men who were followed from 1990 to 2008. Researchers from Harvard University in Boston and the University of Southern Denmark in Odense teamed up to examine the role exercise and weight training had on men's risk for the disease that affects an estimated 346 million people worldwide.
